The ordinary acceptance sampling plans are used to accept or reject the submitted product on the basis of random sample taken from the lot. This sampling scheme is used to test the item one by one. In practice, there are testers accommodating multiple items are available. In this situation, group acceptance sampling is used more efficiently. The basic purpose of group acceptance sampling plans is that it can reduce the cost and the time of the experiment than the ordinary acceptance sampling plans.The group acceptance sampling provides the strict inspection of the product under...

Indiscriminate use of insecticides did not only cause resistance to several insects pests of different crops but it also affected several predators. However Chrysoperla carnea has shown some tolerance to several groups of insecticides in the field but very little informations are available on insecticides resistance in C. carnea. The resistant C. carnea could help to design IPM strategy for several insect pests. Hence several studies were performed in our laboratory to establish if the predator was resistant to insecticides and if the resistance can increase the fitness of C....

The method of paired comparisons is a technique in which the treatments or stimuli are presented in pairs to some respondents, who depending upon sensory evaluation, pick the better one. The experiment is repeatedly executed for all the treatments with a number of respondents to reach certain ranking of the treatments. In this study, an attempt is made to develop paired comparison models, namely the Pareto model and the Cauchy model. The Cauchy model is also extended to accommodate ties. Bayesian analysis is a modern inferential technique which endeavors to estimate parameters of an...

Non availibility of optimum moisture level to crop plants is a major cause of reduction in agricultural productivity in the world. To feed the increasing number of individuals on the earth, there must be a very clearcut objective to develop drought tolerant germplasm. This book will provide you the information about the performance of maize germplasm against different moisture levels and methodology to screen out the best performing maize accessions. Evaluation was made on the basis of survival rate, relative cell injury percentage (RCI%) and stomatal conductance. To visualize the genetic...

Wheat is the most widely grown crop in the world and is sown over a wide range of sowing dates in various cropping systems. Sowing time as a crop management tool played a significant contribution towards the wheat grain yield, reflecting the importance of the selection of optimum sowing time. The genotypes also behaved variably. This book, elucidated some important parameters that can be used as yield predictors of the crop. To further clarify, a validated APSIM model was used for understanding and analyzing optimum sowing time, genotype and climatic behavior. The simulation results explained...

The Bayesian approach to analyze different statistical models has developed great interest among analysts. Posterior distribution is the workbench of the Bayesian statisticians. It is obtained when prior information is combined with likelihood. Therefore the prior information is necessary for the Bayesian approach. The prior information is purely subjective assessment of an expert before any data have been observed. So here we consider different informative and non-informative priors and compare them to see which one is more suitable for our proposed model. The effort of current study is to...

This book focuses on early germination, one of maize germplasm most important strategies for adapting to drought-induced stress. Some genotypes have the ability to adapt by either reducing water losses or by increasing water uptake. Drought tolerance is also an adaptive strategy that enables crop plants to maintain their normal physiological processes and deliver higher economical yield despite drought stress. Several processes are involved in conferring drought tolerance in maize: the accumulation of osmolytes or antioxidants, plant growth regulators, stress proteins and water channel...
